50 Common Latin Phrases Every College Student Should Know
There may not be cites and countries full of people speaking Latin these days, that
doesn’t mean the ancient language is something you can just forget about. Not only are
many of our words in English (not to mention many other languages) derived from Latin,
but many of its words are still used in today’s daily speaking and writing. So while you
may not need to learn to speak or read the Latin language fluently, it can still be a big
help in your quest for higher education to know a few words and phrases. Here are
some of the most commonly used Latin expressions that you should learn to start
improving your personal lexicon.
Must-Learn Terms
If you don’t know these Latin terms, get to learning them ASAP, as they are commonly
used in speaking and writing and may be hard to avoid.
Per se: The direct translation of this term is “by itself” and it means just that when used
in English as well. You could use it to say that you don’t find chemistry boring per se (by
itself, intrinsically), but this professor’s voice puts you to sleep.
Vice versa: From the Latin meaning “to change” or “turn around,” this term means to
reverse the order of something. This quote from Samuel Butler provides an example, “In
the midst of vice we are in virtue, and vice versa.”
Alma mater: If you don’t know this term already, you’ll become quite familiar with it once
you graduate from college. The literal translation is “dear/bountiful mother” but you’ll find
it used in everyday language to denote the college or university from which one has
Magnum opus: Whether it’s in writing, painting, sculpture or music, this Latin term
denotes the greatest work done by an artist– a true masterpiece.
Bona fide: While it’s literal translation means “good faith” this term has a few different
shades of meaning in modern language. In legal terms, it is used to represent something
that is presented without deception or fraud, or literally in good faith, honest, sincere and
lawful. It is more commonly used to mean something that’s the real deal or truly
Quasi: In Latin, this word means as if or as though and in English it is used as both an
adjective in its own right and as a part of a compound word. It simply designates
something that resembles something else but doesn’t quite have all the same features.
Alter ego: Cicero coined this term, most likely taken from the Greek, to mean “a second
self” or “another I” and its modern meaning hasn’t changed much today. Many people
have an alter ego, or another, perhaps hidden aspect of themselves. One example from
popular culture is Beyonce’s alter ego, Sasha Fierce.
Verbatim: If you repeat something verbatim you repeat it in exactly the same words,
word for word with no changes and no improvisation.
Status quo: From the Latin meaning “the state in which” this term is used today to
designate the existing state or condition of things. For example, if you’re making money
off of a high pollution industry it is to your interests to maintain the status quo when it
comes to environmental law.
Knowing just what these terms and words mean can be a big help in improving your
reading comprehension.
Sic: Found in writing, this Latin word most commonly finds a home in brackets (like this:
[sic]) when quoting a statement or writing. It indicates that there is a spelling or grammar
error (or just something out of the ordinary) in the original quotation and that the
publication has only reproduced it faithfully, not made an error of their own.
Id est: You’ve likely seen this term in writing before, even if you weren’t aware as it is
commonly abbreviated to i.e. In Latin, it means “that is” and is used in English when the
speaker or writer wants to give an example or explanation that specifies a statement.
Deus ex machina: In direct translation, this term means, “God out of a machine” and it
harkens back ancient Greek and Roman plays. When the plot would become too tangled
or confusing, the writers would simply bring in God, lowered in via a pulley system (the
machine) and he would wrap it all up. Today, it’s still used in literature to describe a plot
where an artificial or improbable means of resolving a conflict is used.
Exempli gratia: You’ll often see this term abbreviated to e.g. in writing. It means “for the
sake of example” and when it see it in a sentence you can expect that is will be followed
by some examples.
Et cetera: Few out there aren’t familiar with this term but may not know it as well when
it’s spelled out like this and not abbreviated as etc. Meaning “and the others” it is used to
denote that a list of things could continue ad infinitum (see below for definition) and that
for the sake of brevity it’s better to just wrap things up with a simple etc.
Ex libris: Back in the days when books were rarer and more expensive commodities
than they were today, it was common to mark your books with a label bearing your own
name and this phrase which means “from the library of.” While not as common today,
some true bibliophiles still use the labels.
Ibidem: Another abbreviated term, this word is more commonly seen in research writing
in the form of “ibid.” From the Latin for “in the same place” it is found in footnotes and
bibliographies to designate that the same source has been cited twice in succession.
Et alii: You’re unlikely to encounter this Latin phrase in its unabbreviated form, and will
most likely only ever see it as et al when included. This is also a term that is found in
footnotes and bibliographies which allows writers to refer to a large number of authors
without having to write each name out (for example, you could say that your source is
Dr. Henry Jones et al.)
Everyday Talk
You’ve likely heard these words and phrases on the news or in conversations, and if you
didn’t know what they meant then, these definitions will help make it clear now.
Ad infinitum: You might be able to guess what this phrase means simply through its
similarity to the word we use in English. It means “to infinity” and can be used to
describe something that goes on, seemingly or actually endlessly, as some students
might feel about certain classes.
De facto: In Latin, de facto means “from the fact” and in use in English it is often used to
distinguish was is supposed to be the case from what is actually the reality. For
example, legally, employers are not allowed to discriminate in hiring because of age, but
many still practice de facto (in reality, in fact) discrimination.
In toto: No, this phrase doesn’t mean that the cute little dog from The Wizard of Oz ate
something, it means in all or entirely. Think of it as saying “in total” in a really weird voice.
Ipso facto: Meaning “by the fact itself” this commonly used and misused term is denotes
when something is true by its very nature. For example, if you don’t feed your dog you
are ipso facto a bad owner.
Tabula rasa: When you were a child, your mind might have been more of a tabula rasa
than it is today. This Latin phrase means “clean slate” and denotes something or
someone not affected by experiences and impressions.
Terra firma: Those who hate to fly or get seriously seasick will be able to put this term to
good use. It means firm ground, and you might be thanking your lucky stars to be back
on it after a trip through the air or rough waters.
Mea culpa: If you want to admit your own guilt or wrongdoing in a situation, use this
Latin phrase that translates literally to “my fault.” It’s a bit like a fancier, less outdated
way of saying “my bad.”
Persona non grata: From the Latin meaning an “unacceptable person” this term
designates someone who’s no longer welcome in a social or business situation.
In situ: If something happens in situ it happens in place or on site, though the term often
designates something that exists in an original or natural state. Like a rare species
sighted in situ or an invaluable artifact found on an archeological site.
In vitro: Most students will be familiar with this term because of modern fertility
treatments, but have you ever considered what the term actually means? In Latin, in
vitro means “in glass” and any biological process that occurs in the laboratory rather
than in the body or a natural setting can be called in vitro.
In vivo: While an experiment taking place in a glass test tube might not cause a stir,
many are up in arms about this kind of experimentation. In vivo means “within the living”
and the two most common examples of this kind of experimentation are animal testing
and clinical trials.
Ante bellum: During your history courses, you’re bound to encounter this term. It means
in the most basic sense “before the war” and while it can be applied to any war it is most
commonly used to refer to the American Civil War and the Antebellum Era the preceded
Arguments and Logic
Representing arguments as old as philosophy itself and the terms associated with them,
these terms are good to know for a well-rounded education.
A priori: You might come across this term in classes about logic or reasoning. It means
taking a general law or idea and applying it to a particular instance without needing
experimentation or observation. An example of an a priori statement that is used is, “all
bachelors are single.” You do not need to observe this to see that it is true because, by
definition, bachelors must be single.
A posteriori: A posteriori arguments are different than a priori because they are based
on actual observation or experimentation. Continuing on the previous example, an a
posteriori example of reasoning might be that “some bachelors are happy.” This can be
based on real life observation isn’t a given based on what a bachelor is.
Ad nauseam: This Latin term is used to describe an argument that has been taking
place to the point of nausea, often with the same arguments being rehashed over and
over for years until everyone, except a select few, are simply sick to death of the whole
Ergo: Simply put, ergo means therefore and you can exchange it with therefore or
hence in any sentence and maintain the same meaning. For example, you could say, “I
think, ergo I am” without changing the meaning of the original.
Legal Language
One place where Latin words are very commonly used is in the courtroom. Learn some
of these basic legal words to help you better understand Law and Order and how the
legal process works.
Compis mentis: Meaning “in command of one’s mind” this term is used in the legal field
to denote someone who is competent to stand trial and not encumbered by mental
illness or handicap.
Subpoena: If you’ve ever watched a legal drama on TV, you’ve more than likely heard
this term thrown around but perhaps haven’t given much thought as to what it really
means. The word subpoena comes from the Latin meaning “under penalty” and if
someone delivers a subpoena to you have to respond or they’ll be some big penalties
under the law.
Ad hominem: In court, or outside of it for that matter, this term is used to designate an
argument that attacks someone’s character rather than addressing a question or issue at
hand. By attacking character, these arguments appeal to emotions and prejudices rather
than reason or logic.
Habeas corpus: A writ of habeas corpus (literally, have the body) requires a person to
appear before the court in person, generally to ascertain whether or not the detention of
that person is lawful. Habeas corpus cannot be suspended unless there is reason to
believe that a person could pose a danger to the public.
Pro bono: Pro bono means “for the good” and it’s a term used to designate when
something is done free of charge. While the term can be applied in any field, it is most
commonly used to describe legal services.
Mens rea: There is a big difference between murder and manslaughter, and mens rea is
what separates the two. Mens rea means “guilty mind,” and those who go into a crime
intending to commit it have it, differing from those who commit a crime accidentally or
without advance planning.
It’s always good to know the language of business, especially in such a competitive
market. No matter what field you enter, you’re bound to hear these words at some point
in your career.
Ad hoc: From the Latin meaning “to this,” this term gained popularity in the mid-1600s
and it still used today. It refers to something that is formed or done quickly to meets the
needs of a particular problem or issue without regard to a more general application and
generally lacking advance planning.
Per diem: Meaning “by the day” a per diem in most uses today designates a daily
allowance used in traveling for work. It can also mean a per-day rate or that someone is
paid on a daily basis. Other common similar terms are per annum (by the year) and per
capita (by the person.)
Curriculum vitae: A curriculum vitae is basically a fancy way to describe a resume.
While it means literally “the course of one’s life” the terms is applied to mean a short list
of your accomplishments and training– something any grad will need to think about
putting together soon.
Pro rata: This Latin phrase is something you’re likely familiar with in everyday life. It
means to charge at a proportional rate. So if a service is $100 for 10 hours, then one
would cost $10 pro rata.
Quid pro quo: While Anthony Hopkins so sinisterly used this phrase in The Silence of
the Lambs, in everyday life it’s often used to describe an exchange of value necessary
for a contract to take place. From the Latin meaning “this for that,” it gets used in
everywhere from the courtroom to the bedroom in modern English.

repeated in conversations so they’re well-worth knowing.

been arguments about the exact translation, it is most commonly held to mean “seize the

and comes from the writing of philosopher Rene Descartes.

Julius Caesar after a short war with Pharnaces II of Pontus. Translated, it means “I
came, I saw, I conquered” an adage you can hopefully keep in mind come finals time.
In vino veritas: If you’re old enough to drink or have been around others who have
imbibed, you’re more than likely already familiar with the wisdom behind this quote from
Pliny the Elder meaning, “in wine there is the truth.” It is often followed up with “in aqua
sanitas” or “in water there is health”– something all college students should remember.
E pluribus unum: Simply take a look at American currency to see this Latin phrase in
